“Peter Pan Live!”, based on the classic musical originally associated with Mary Martin, will air tonight on NBC. It follows the network’s massively successful live airing last year of “The Sound of Music.” I wish the network well. I suspect the ratings won’t be quite as boffo as last year’s, which had the advantage of Carrie Underwood and her big fan base. But I’m sure “Peter” will do just swell, and millions will have fun watching and tweeting reactions to every shot. I’m sorry there’s not a live audience this year — the lack of one resulted in a lot of dead space in last year’s show. But NBC learned from last year in terms of presentation: many more cameras will be used tonight. Enjoy!
